Title: Method of and a mold for injection molding of articles made of a thermoplastic material and the walls of which enclose a hollow space
Inventor: ECKARDT HELMUT
IPC: B29C45/17
Filed: 1993-10-01
Granted: 2004-05-04
Abstract: Proposed is a process for injection molding of products (1) made of thermoplastic material, whose walls (2) enclose a hollow space (3), wherein the molten plastic is injected in a predetermined amount into the cavity or molding nest (6) of a mold (5), during and/or upon which a fluid pressure medium (gas) is applied so that with the formation of the hollow space the molten plastic is distributed along and set against the walls of the cavity or molding nest. The pressure medium (gas) is fed into the cavity or molding nest (6) and into the molten plastic at first essentially only in the direction of flow of the molten plastic and in a quantity and/or at a pressure that causes a void (8) to form within the molten plastic, terminating at a distance from the end of the flow path. Then, with a time lag, more pressure medium (gas) at a higher or increased level of pressure is fed into the cavity and the molten plastic from the end of the flow path for the molten plastic and essentially counter to the direction of flow of the molten plastic, forming a second void (11) which joins with the already existing void (8).

Abstract: In order to measure an individual time interval with accuracy be-yond frequency limit of semiconductors, a time measurement system of the invention generates a series of delayed pulses, each of which has the same pulse width with the time interval to be measured and delayed by a unit delay time shorter than a cycle time of a system clock from its preceding delayed pulse.    A series of discriminate number measurement pulses are also gen-erated from the series of delayed pulses, each of which rises at a com-mon time and falls at each corresponding delay pulse.    From number of a longest sequence of the same pulse number of the system clock counted in the discriminate number measurement pulses, the unit delay time is measured.    From average value of pulse numbers of the system clock counted in each of the delayed pulses, the time interval to be measured is cal-culated with accuracy of the unit delay time.
